Send communications through Openapi - SMS with custom sender and OTP (SMS v2), Italian certified e-mail (PEC/Legalmail), bulk certified mail (Massive REM), and physical mail via Poste Italiane (registered letters, telegrams, judicial acts). Use when the user wants to send a message, letter or certified communication.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Openapi messaging & communications
All services use a Bearer token (see the `openapi-auth` skill). **Every send is an outward-facing, paid action: always confirm recipient, content and cost with the user before sending.**
## SMS v2 — `https://sms.openapi.com`
- `POST /IT-messages` (Italy), `POST /ES-messages` (Spain), `POST /WW-messages` (worldwide)
- `POST /otp` — OTP verification messages
- `GET /messages`, `GET /messages/{id}` — sent messages and delivery status
Features: custom sender, E.164 validation, GSM-7/UCS-2 detection with automatic segmentation, **`dry_run` for free testing**, webhook delivery callbacks. Messages expire after 48h (status `EXPIRED`). Worldwide pricing is computed post-sending and requires a minimum credit balance. SMS v1 (`ws.messaggisms.com`) is **deprecated**.
```bash
curl -s -X POST https://sms.openapi.com/IT-messages \
-H "Authorization: Bearer $OPENAPI_TOKEN" \
-H 'Content-Type: application/json' \
-d '{"sender": "MyBrand", "body": "Hello!", "recipients": ["+39333…"], "options": {"dry_run": true}}'
```
## PEC (certified e-mail) — `https://pec.openapi.it`

How to install
mdr add openapi/openapi-skills/openapi-messaging@sha256:897b65d4583869adThe line at the top of this page pins the label git:20260610.0dfad19, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
